WebGenetic code can be referred to as a dictionary that recognizes the correspondence between the nucleotide sequence in a gene and the sequence of amino acids in a … WebThe genetic code consists of the sequence of nitrogen bases in a polynucleotide chain of DNA or RNA. The bases are adenine (A), cytosine (C), guanine (G), and thymine (T) (or uracil, U, in RNA). The four bases make up the “letters” of the genetic code. The letters are combined in groups of three to form code “words,” called .

WebThe genetic code is degenerate. There are four bases, so there are 64 different codons (triplets) possible (4 3 = 64), yet there are only 20 amino acids that commonly occur in biological proteins . This is why the code is said to be degenerate: multiple codons can code for the same amino acids; The degenerate nature of the genetic code can limit the … WebAdenine (“A”) and Thymine (“T”) each have one donor and one acceptor, whereas Cytosine (“C”) has one donor and two acceptors, and Guanine (“G”) has one acceptor and two donors. The A nucleotides are always hydrogen bonded to T nucleotides, and C nucleotides are always hydrogen bonded to G nucleotides.
